Exam 300-415 topic 1 question 345 discussion

Logged into vManage: Local policy > "create groups of interest" > Class Map is shown > Add Class list.

B is correct. Mind the question: 'creating a class map and assigning it to the LLQ queue'. Class maps are created under local policy/lists and there you can assign queue 0. D is false because there you create QOS maps which will already have queue 0 populated with the class map created for it.

I also think it B, from the following link https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/qos/ios-xe-17/qos-book-xe/forwarding-qos.html Map Each Forwarding Class to an Output Queue From the Cisco SD-WAN Manager menu, choose Configuration > Policies. From the Custom Options drop-down, select Lists under Localized Policy. Select the Class Map from the list types. Click the New Class List. The Class List pop-up page is displayed. Enter a name for the class. Select a required queue from the Queue drop-down list. Click Save

D based on Cisco page https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/qos/ios-xe-17/qos-book-xe/forwarding-qos.html#Cisco_Concept.dita_bce41c9c-323f-4a04-af08-38604e5de0ee

D is correct

QoS policy belongs to Localized Policy. So, A and C options eliminates. B is correct answer. Reference: CBT Nuggets SDWAN video course (instructor Knox Hutchinson)
